Abstract
The present invention relates to a kind of production methods of rubber slab, and waste Crumb rubber is broken into the rubber powder lower than 60 mesh, and vulcanization accelerator, vulcanizing activator, sulphur, diatomite, magnesium stearate, anti-aging agent and vulcanizing agent is then added, vulcanized after mixing to get；By rubber powder be 100 parts by weight in terms of, vulcanization accelerator be 0.8-1.2 part, vulcanizing activator be 2-5 part, sulphur be 5-8 part, diatomite be 12-18 parts, magnesium stearate be 1-3 parts, anti-aging agent be 3-6 parts, vulcanizing agent be 2-4 parts.Production method of the invention is simple, the pollution of waste water, exhaust gas, dust is not present convenient for operation, and in technical process, and rubber slab mechanical strength obtained is high, and adhesion strength is high, and resistance to ag(e)ing is good, is suitable for desulphurization system, and at low cost.
Description
Technical field
The present invention relates to a kind of production methods of rubber slab, belong to rubber product technical field.
Background technique
In the canister inner wall and steel pipe internal-surface of desulphurization system, it is required to sticker rubber plate, i.e., in metal in rubber
Plate adhesive surface respectively applies one layer of rubber cement, then is vulcanized, and rubber slab is made to be fixed on metal surface.
In the prior art, common Natural rubber sheet is mostly used to be pasted, cost is relatively high, and rubber slab obtained with
The adhesion strength of metal surface is low.It is subject to benefit after waste old is prepared rubber powder by the methods of ambient ground or low-temperature grinding
With being a kind of very important approach of current waste old recycling.Usually i.e. by scrap rubber through crushing, desulfurization, roll refining etc.
Process thoroughly removes the sulphur in scrap rubber, restores the due elasticity and plasticity of rubber, to form reclaimed rubber.The method is deposited
In the disadvantage that energy consumption is high, and low efficiency, process flow are grown, and limited in view of current technology and economic condition, many regeneration in China
The scrap rubber of glue enterprise takes off sulphur regeneration process and there is different degrees of low-concentration organic exhaust gas, be easy to cause atmosphere pollution.
Summary of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of a kind of production methods of rubber slab.
Technical solution
A kind of production method of rubber slab: being broken into the rubber powder lower than 60 mesh for waste Crumb rubber, and vulcanization accelerator, vulcanization is then added
Activating agent, sulphur, diatomite, magnesium stearate, anti-aging agent and vulcanizing agent, vulcanized after mixing to get；It is with rubber powder
100 parts by weight meters, vulcanization accelerator are 0.8-1.2 parts, and vulcanizing activator is 2-5 parts, and sulphur is 5-8 parts, diatomite 12-18
Part, magnesium stearate is 1-3 parts, and anti-aging agent is 3-6 parts, and vulcanizing agent is 2-4 parts.
Further, the vulcanizing activator is the mixture of magnesia and zinc oxide 1:2.
Further, curing temperature is 135~145 DEG C, and pressure is 6~8Mpa, time 20-25min.
Production method of the invention is simple, the dirt of waste water, exhaust gas, dust is not present convenient for operation, and in technical process
Dye.Rubber slab mechanical strength obtained is high, and adhesion strength is high, and resistance to ag(e)ing is good, is suitable for desulphurization system, and at low cost.
Specific embodiment
The present invention is further explained in the light of specific embodiments.
Embodiment 1
Waste Crumb rubber is broken into the rubber powder lower than 60 mesh, vulcanization accelerator, vulcanizing activator, sulphur, diatomite, hard is then added
Fatty acid magnesium, anti-aging agent and vulcanizing agent under conditions of temperature is 140 DEG C, pressure is 7MPa, vulcanize 22min after mixing,
To obtain the final product；By rubber powder be 100 parts by weight in terms of, vulcanization accelerator be 1 part, the vulcanizing activator (mixing of magnesia and zinc oxide 1:2
Object) it is 3 parts, sulphur is 6 parts, and diatomite is 15 parts, and magnesium stearate is 2 parts, and anti-aging agent is 5 parts, and vulcanizing agent is 3 parts.
